Good learning solution for marketing and sales teams

Grinfer Business is a solution our company uses to help us upskill and get new knowledge for more effective work. The best thing about it is that the platform has dozens of courses on various topics, which all are available to us. The library of business courses is great including marketing and sales (it was really helpful), and I can manage the pace myself and determine the most necessary skills to get myself. Unfortunately, there're no courses on influencer marketing, which I do, so I can't learn anything new on this topic. The platform allows us to send requests for courses but they haven't added anything on this topic so far. Anyway, I managed to learn a lot on complementary subjects and support has been helpful to get the necessary guidance.
